BACKGROUND 1. Technical Field

The present invention relates to an image processing system in which animage processing device transmits and receives information related toimage processing to and from a communication device through wirelesscommunication. In particular, the present invention relates to an imageprocessing device capable of improving operability and an imageprocessing system including the image processing device.

2. Description of Related Art

Portable communication devices, so-called smartphones, have widely beenused. This kind of communication device is highly convenient since it isable to have various functions by adding various applications inaddition to functions such as a camera, a game, and a media player.

Recently, techniques in which a communication device is connectedthrough wireless communication to a network where an MFP (Multi-FunctionPeripheral) provided with a wireless communication function is connectedand in which the communication device transmits and receives informationto and from the MFP have widely been used. In particular, a system hasbeen realized that it is possible to directly print out image data by anMFP without using a storage medium, a USB (Universal Serial Bus) cable,a personal computer or the like by transmitting the image data to theMFP in a network through wireless communication from a communicationdevice having a camera function. In addition, mechanisms in which an MFPtransmits image data obtained by reading a document to a communicationdevice also have been suggested.

Operations such as registering information of a network connected to anMFP into a communication device for establishing communication betweenthe communication device and the MFP to transmit and receive data eachother are required of a user. Moreover, in order to cause the MFP totransmit data to a communication device, a user has to operateregistration of the address information of the communication device intothe MFP. In a case where such an operation is complicated, a user mayperform an erroneous operation and may keep away from using the MFP.Accordingly, it is required to resolve a complicated operation.

Japanese Patent Application Laid-Open No. 2007-300480 discloses aninvention capable of displaying one-touch keys for a user and an addressbook to an MFP connected to a LAN (Local Area Network) when the useroperates a drag-and-drop operation of a setting file into a settingscreen of a web browser on a client PC (personal computer) connected tothe LAN.

SUMMARY

Since a portable information terminal device capable of directlycommunicating with an MFP has been realized, it is required to provide aconfiguration with further improved operability omitting a settingoperation or the like as much as possible and easier utilization. Theinvention disclosed in Japanese Patent Application Laid-Open No.2007-300480 can only display an operation screen set for a user, and auser still has to perform an operation for generating a setting forhim/herself.

According to the present invention, in a case where a communicationdevice is connected to an image processing device accepting an operationcorresponding to an operation screen to execute image processing, theimage processing device alters the displayed screen to an operationscreen for image processing related to information transmitted/receivedto/from the communication device. Therefore, operation for causing theimage processing device to execute transmission/reception of informationto/from the communication device and to execute information processingrelated to the information can be simplified.

According to the present invention, in a case where a function ofgenerating image data and a function of transmitting the generated imagedata to a communication device connected to an image processing deviceor to other devices have been realized in the image processing device,an operation screen including an interface for accepting an instructionto generate image data is automatically displayed in a display unit ofthe image processing device. Therefore, it is possible for a user toeasily use the function.

According to the present invention, in a case where an instruction togenerate image data is accepted through an interface included in anoperation screen after alternation, image acquisition information(hereinafter referred to as “reference information”) for obtaining thegenerated image data from a communication device connected to the imageprocessing device or from other communication devices is automaticallyprepared. Therefore, a variety of settings for receiving information ina communication device can be omitted.

According to the present invention, in a case where a function ofprinting based on image data obtained from a communication deviceconnected to an image processing device or from other devices have beenrealized in the image processing device, an operation screen includingan interface for accepting an instruction to print is automaticallydisplayed in a display unit of the image processing device.

Since the reference information as described above isprepared in the image processing device, the operation of the externalcommunication device can be simplified.

According to the present invention, an image processing device mayautomatically obtain a list of image data to be printed from acommunication device being connected or from an external deviceincluding other communication device and may display the list so as tobe selectable in the display unit. Therefore, the operation until theexecution of printing can be simplified.

In a case of returning an operation screen to the operation screen indefault after the communication with a communication device is cut off,it may be configured to return the operation screen when a user confirmsan alternation and selects an alternation. In this case, the user'soperation can be simplified.

Moreover, even if a communication device is connected to an imageprocessing device, in a case where an operation is not performed for aprescribed period or longer, a screen may be configured to be returnedto an original predetermined operation screen so that accepting anerroneous operation can be prevented.

An operation related to image processing in an image processing devicemay be accepted only in a case where a communication device is connectedto the image processing device from outside through wireless connection.Therefore, it is possible to prevent the complication of the operationrelated to image processing.

According to the present invention, since an operation in an imageprocessing device is automatically altered in response to the presenceor absence of a communication device connected to the image processingdevice through wireless communication, the operation of image processingrelated to wireless communication can be simplified. This can furtherimprove user operability. In addition, the connection with only onecommunication device is controlled to be established so that thecomplication of image processing based on information transmitted from aplurality of communication devices can be prevented.

The following will describe in detail the present invention withreference to the drawings illustrating some embodiments thereof.

Embodiment 1

FIG. 1 is a schematic view showing a configuration of an imageprocessing system according to Embodiment 1 and FIG. 2 is a block viewshowing the configuration of the image processing system according toEmbodiment 1. The image processing system includes an MFP(Multi-Function Peripheral) 1 installed in an enterprise, a publicfacility, a house or the like and a communication device 2 carried by auser. The MFP 1 directly establishes a connection through wirelesscommunication with one communication device 2 existing in an effectivearea of wireless communication in an ad-hoc mode. The MFP 1 may also beconnected to a LAN in an enterprise, a public facility, a house or thelike in addition to a communication connection with the communicationdevice 2, or it may also be connected to an external internet.

According to the present invention, the operation to be performed by auser carrying the communication device 2 can be simplified as much aspossible while the MFP 1 executes scanning or printing based oninformation from the communication device 2 carried by a user in theimage processing system.

The MFP 1 is an image processing device provided with a reading function(a scanner), a printout function (a printer), a FAX function and thelike to execute processing for image data. The MFP 1 includes a controlunit 10 controlling each of configuration units, an input/output unit 11using a touch panel and a Liquid Crystal Display (LCD), a temporarystorage unit 12, a storage unit 13 storing various types of information,a communication unit 14 realizing communication with the communicationdevice 2, an image reading unit 15 realizing a reading function, and animage forming unit 16 realizing a printout function. The MFP 1 hasconfiguration units for realizing many functions such as a FAXcommunication unit executing FAX communication through a telephonenetwork, which will not be illustrated or described here in detail.

The control unit 10 uses a CPU (Central Processing Unit) to controlvarious configuration units based on control programs stored in abuilt-in ROM (Read Only Memory).

The input/output unit 11 includes a display unit 11 a using an LCD andan operation unit 11 b using a touch panel. For the operation unit lib,not only a touch panel but hardware keys may also be used. With respectto the display unit 11 a displaying an operation screen includingvarious kinds of icons or buttons and accepting an operation from auser, the operation unit 11 b detects a position (an operating position)on the touch panel touched by a user. The control unit (accepting unit)10 is able to identify which icon or button has been touched based onthe information of the position touched by a user and the positionalinformation of the icons or buttons displayed in the display unit 11 a.It is also possible for the control unit 10 to identify which hardwarekeys has been pressed.

The temporary storage unit 12 uses a RAM such as a DRAM (Dynamic RandomAccess Memory), an SRAM (Static Random Access Memory) or the like. Thetemporary storage unit 12 stores temporary information for a variety ofprocesses generated in the processing of the control unit 10. Inaddition, the temporary storage unit 12 stores an access key (permissioninformation) for accessing a scanner or printer function of the MFP 1through wireless communication. The access key will be detailed later.

The storage unit 13 uses an HDD (Hard Disk Drive) or an SSD (Solid StateDrive). The storage unit 13 may store address information for a FAXfunction, an e-mail communication function, and an FTP (File TransferProtocol) communication function. The storage unit 13 may also store,for example, image data read by the image reading unit 15 or image datareceived through the communication unit 14.

The communication unit 14 realizes a wireless communication function.The control unit 10 is able to transmit and receive data to and from thecommunication device 2 through wireless communication by thecommunication unit 14. The communication unit 14 is configured toconnect to one communication device 2 in an ad-hoc mode and configurednot to connect to a plurality of communication devices 2 at the sametime. The communication unit 14 has an access point function, that is, abase unit function in a wireless LAN system. The communication executedby the communication unit 14 is not restricted to an ad-hoc mode. If astate where the communication unit 14 is connected to a plurality ofcommunication devices 2 at the same time can be eliminated, othermethods can also be adopted. The communication unit 14 may be aninterface such as a non-illustrated USB (Universal Serial Bus) includedin the MFP 1, in this case, the communication may be realized byconnecting a wireless communication device having an access pointfunction to the interface.

For the image reading unit 15, a scanner unit is used. The scanner unitis a reading device for optically reading a document placed on a scannerplaten 15 a or a document tray, and the scanner unit includes an opticalunit and a control unit for controlling a reading operation executed bythe optical unit inside the main unit of the MFP 1. The image readingunit 15 outputs image data obtained by reading a document to apredetermined image memory, so that the control unit 10 is able toobtain the image data from the image memory.

For the image forming unit 16, a printer unit is used. The printer unitis disposed below the scanner unit inside the main unit of MFP 1. Theprinter unit generates a toner image based on image data given from thecontrol unit 10, and transfers the toner image onto a sheet of paper toexecute image formation.

The communication device 2 corresponds to a portable telephone machine,i.e. a so-called smartphone. The communication device 2 may also be atablet PC (personal computer). The communication device 2 includes acontrol unit 20 controlling each of configuration units, an input/outputunit 21 using a touch panel, a storage unit 22 storing various types ofinformation, and a communication unit 23 realizing communication withthe MFP 1 via the access point AP.

The control unit 20 uses a CPU to control each of configuration unitsbased on control programs stored in a built-in ROM.

The input/output unit 21 includes a display unit 21 a using an LCD andan operation unit 21 b using a touch panel and hardware keys. Withrespect to the display unit 21 a displaying various kinds of icons orbuttons, the operation unit 21 b detects a position on the touch paneltouched by a user and notifies the control unit 20 of the information ofthe position touched by the user. The control unit 20 is able toidentify which icon or button has been touched based on the positionalinformation of the icons or buttons displayed in the display unit 21.When a hardware key is pressed, the operation unit 21 b notifies thecontrol unit 20 of information for identify which key has been pressed.

The storage unit 22 uses a RAM and a flash memory. In the flash memoryof the storage unit 22, an application program (hereinafter referred toas a print scanning application) used for printing (printout) an imagedata or for reading (scan) a document in the MFP 1 connected to thenetwork N is stored. The control unit 20 reads out and executes theprint scanning application stored in the storage unit 22, to realizecommunication with the MFP 1 and transmission/reception of image datato/from the MFP 1, which will be described later.

Furthermore, the storage unit 22 stores the setting information such assetting for resolution of the image data to be received, a file type(format), color/monochrome, size of an document to be read and size ofimage data to be generated (the presence or absence of reduction) so asto correspond to the print scanning application. The setting informationmay include a print size setting for printing based on image data to betransmitted, a color/monochrome setting, a printing quality setting orthe like. The setting information is initially set in the print scanningapplication and may later be edited by the user through the printscanning application. The setting information may be stored individuallyin each of different MFPs. The username (user ID) of the communicationdevice 2 may also be included in the setting information.

In the storage unit 22, image data may be stored in the flash memory.The control unit 20 can transmit image data stored in the flash memoryof the storage unit 22 to the MFP 1 through the communication unit 23.In addition, the image data received through the communication unit 23may be stored either temporarily in the RAM of the storage unit 22 orthe flash memory for saving.

In the storage unit 22, information of an address book is stored in theflash memory. The control unit 20 can also transmit an e-mail by a mailfunction based on the information of the address book stored in theflash memory of the storage unit 22.

The communication unit 23 realizes a wireless communication function.The communication unit 23 can connect to the communication unit 14 ofthe MFP 1 and transmit/receive a variety of information including imagedata to/from the MFP 1 based on the instruction obtained from thecontrol unit 20.

In the image processing system configured as described above, theprocedure for altering a screen to be displayed in the MFP 1 when thecommunication device 2 is connected to the MFP 1 will be described withreference to the flowchart and examples of operation screens.

FIG. 3 is a flowchart showing an example of a screen alternationprocedure to be executed in the MFP 1 according to Embodiment 1.

The control unit 10 of the MFP 1 determines whether a connection requestfrom the communication device 2 has been received through thecommunication unit 14 (Step S11). If the control unit 10 determines thatthe connection request has not been received (S11: NO), the control unit10 returns the processing to Step S11, and then waits until it isdetermined that the connection request has been received.

Meanwhile, the control unit 20 of the communication device 2 searchesfor an access point, that is, the communication unit 14 of the MFP 1,obtains identification information such as SSID of the MFP 1, andtransmits the connection request to the MFP 1 based on the obtainedidentification information. The control unit 20 may obtain the SSID ofthe MFP 1 directly inputted by a user through the operation unit 21 bwithout performing a search.

At Step S11, if the control unit 10 of the MFP 1 determines that theconnection request has been received (S11: YES), the control unit 10issues network identification information of the communication device 2to establish a wireless communication connection with the communicationdevice 2 (Step S12), and then transmits the network identificationinformation to the communication device 2 (Step S13). As the networkidentification information, for example, the control unit 10 assigns anIP address such as “192.168.0.20” to the communication device 2 in acase where the IP address of the communication unit 14 of the MFP 1 is“192.168.9.10.” Therefore, a wireless communication connection isestablished between the MFP 1 and the communication device 2, and thecontrol unit (connection detecting unit) 10 of the MFP 1 detects aconnection with the communication device 2.

Next, the control unit (altering unit) 10 alters the operation screendisplayed in the display unit 11 a to an operation screen related toimage processing based on the information transmitted/received to/fromthe communication device 2 (Step S14), and then waits.

Subsequent to Step S14, the control unit 10 accepts an operationcorresponding to the operation screen after alternation (Step S15),executes image processing such as scanning by the image reading unit 15or printing by the image forming unit 16, in response to the operation(Step S16), and then terminates processing.

FIG. 4 is an explanatory view showing an example of an initial screen tobe displayed in the display unit 11 a of the MFP 1. In the initialscreen (default screen), icons 110 to 113 indicating functions notrequiring the communication device 2 among a variety of functionsexecutable by the MFP 1 are displayed. In the screen example shown inFIG. 4, the initial screen includes the icon 110 for starting a copy,the icon 111 for executing scanning (image reading), the icon 112 forexecuting printing (printout), and the icon 113 for selecting andediting address information to be registered in the storage unit 13 ofthe MFP 1. When a user touches the touch panel on any one of icons 110to 113, each of functions can be executed in the MFP 1. For example,when a user touches the touch panel on the icon 110 with a finger or thelike, the control unit 10 detects the action and displays an operationscreen including setting information for executing a copy function inthe display unit 11 a.

FIG. 5 is an explanatory view showing an example of an operation screenof a copy function. When the copy function is selected, pull-down menuswhich can be used for setting the document size, zoom level, number ofcopies and the like as well as a copy start button for executing a copyare displayed in the display unit 11 a as shown in FIG. 5. When a usertouches the touch panel on the copy start button after setting eachitem, a copy of a document placed on the scanner platen 15 a can beprinted out.

A screen to be altered from the initial screen shown in FIG. 4 byconnecting the communication device 2 to the MFP 1 will be described.FIG. 6 is an explanatory view showing an example of the screen afteralternation to be displayed in the display unit 11 a of the MFP 1. Inthe example of the screen shown in FIG. 6, an icon 114 named “mobilescan” and an icon 115 named “mobile print” are added to the initialscreen shown in FIG. 4. As a user touches the touch panel on the icon114, the MFP 1 can execute a function of supplying image data obtainedby scanning a document to the communication device 2 or othercommunication devices. In addition, as a user touches the touch panel onthe icon 115, the MFP 1 can execute a function for printing based onimage data stored in the communication device 2 or other communicationdevices. For example, in the state of displaying the screen shown inFIG. 6 in the display unit 11 a, when a user touches the touch panel onthe icon 114, the control unit 10 detects the action and displays anoperation screen for executing a mobile scan function in the displayunit 11 a.

FIG. 7 is an explanatory view showing an example of an operation screenof a mobile scan function. When the mobile scan function is selected, asshown in FIG. 7, a pull-down menu which can be used for setting the sizeof a document to be read, a file format of image data to be generated,and a color/monochrome setting and the like as well as a scan startbutton (interface) for executing scanning are displayed in the displayunit 11 a. The pull-down menu may also include resolution when reading,a compression format, a compression ratio and the like. When a usertouches the touch panel on each item in the pull-down menu, the controlunit 10 displays selectable choices for each of the items to obtain theselected information. Therefore, a user can edit setting information forscanning. As a user touches the touch panel on the scan start buttonafter setting each of the items, the scanning of a document placed onthe scanner platen 15 a is started.

When the control unit 10 of the MFP 1 detects through the operation unit11 b that the touch panel on the scan start button displayed in anexample of a screen shown in FIG. 7 is touched, the control unit 10reads a document placed on the scanner platen 15 a by the image readingunit (generating unit) 15, to generate image data. In other words, atStep S16 in the processing procedure shown in the above-describedflowchart, the control unit 10 generates image data by reading thedocument and executes processing for transmitting the generated imagedata to the communication device 2 based on the issued networkidentification information.

Therefore, a user can easily recognize and select an interface forrealizing a function related to the communication device 2 through theoperation screen altered by the connection with the communication device2 carried by the user. The MFP 1 can issue network identificationinformation to the communication device 2 through an access pointfunction and identify a destination. Thus, while transmitting image dataobtained by executing scanning, it is not necessary for a user toperform an operation such as operating the operation unit lib of the MFP1 to register destination information. Since the communication device 2and the MFP 1 execute communication in an ad-hoc mode, the connectionswith communication devices carried by a plurality of users respectivelyare not intermingled. Accordingly, while one user operates the MFP 1 towhich the communication device 2 is connected, the user carrying anothercommunication device 2 cannot operate the MFP 1 so that erroneoustransmission will not occur.

Embodiment 2

According to Embodiment 2, the MFP 1 executes processing for requestingthe communication device 2 to transmit information related to adestination to be supplied an image data or image data stored in thecommunication device 2 or a variety of information stored in thecommunication device 2, and executes processing based on the informationreceived from the communication device 2.

A hardware configuration in an image processing system according toEmbodiment 2 is similar to the configuration according to Embodiment 1.Accordingly, the configuration units common to those in Embodiment 1 aredenoted by the same reference numerals and will not be described indetail.

FIG. 8 is a flowchart showing an example of a processing procedure to beexecuted in the image processing system according to Embodiment 2.

A control unit 20 of the communication device 2 searches for an accesspoint through a communication unit 23 in a case where a print scanningapplication is activated (Step S201). The control unit 20 displaysinformation of the access point being a search result in the displayunit 21 a (Step S202), and accepts a selection of the access pointcorresponding to an MFP 1 (Step S203). The control unit 20 transmits aconnection request to the access point of the MFP 1 (communication unit14) (Step S204). At Step S204, the control unit 20 of the communicationdevice 2 transmits a connection request including an execution requestindicating the content of image processing in a case where imageprocessing to be executed in the MFP 1 such as scanning or printing isdetermined.

The control unit 10 of the MFP 1 receives the connection request fromthe communication device 2 (Step S205), and issues networkidentification information of the communication device 2 to establish awireless communication connection with the communication device 2 (StepS206). The control unit 10 transmits the issued network identificationinformation to the communication device 2 (Step S207).

The control unit 20 of the communication device 2 receives thetransmitted network identification information (Step S208). Therefore,the wireless communication connection is established between the MFP 1and the communication device 2.

The control unit 10 of the MFP 1 determines whether obtaininginformation from the communication device 2 is required based on theconnection request (Step S209). For example, in a case where anexecution request is included in the received connection request, and ina case where the content of image processing indicated by the executionrequest is scanning of image data and a transmission of the image datato the communication device 2, the control unit 10 determines that theinformation (setting information) for executing scanning is necessary.

In a case where the control unit 10 determines that obtaininginformation is not required (S209: NO), the control unit 10 alters thescreen displayed in the display unit 11 a to an operation screen relatedto image processing based on the information transmitted/receivedto/from the communication device 2 (Step S210), and then waits. Theoperation screen displayed at this moment, for example, is the screen towhich selectable functions have been added in response to the connectionwith the communication device 2 as shown in FIG. 6.

At Step S209, if the control unit 10 determines that obtaininginformation is required (S209: YES), the control unit 10 transmits atransmission request of the required information to the communicationdevice 2 (Step S211).

In the communication device 2, the control unit 20 receives thetransmission request from the MFP 1 through the communication unit 23(Step S212), and transmits information in response to the receivedtransmission request (Step S213). For example, the control unit 20transmits setting information read from the flash memory of the storageunit 22 through the communication unit 23.

The control unit 10 of the MFP 1 receives the information requested atStep S211 (Step S214), and temporarily stores the received informationin the temporary storage unit 12 (Step S215). The control unit 10 altersan operation screen based on the received information (Step S216) andthen waits. The operation screen displayed at this moment, for example,corresponds to an operation screen in response to the function to beexecuted, as shown in FIG. 7.

Therefore, it is possible to simplify the operation to be performed by auser in the MFP 1 and the communication device 2.

At Step S209, the following example is considered as information havingneed to obtain from the communication device 2.

As described above, the control unit 10 of the MFP 1 requires settinginformation used when executing image processing by a mobile scan, thatis, the image reading unit 15. The setting information is informationsuch as the size of a document to be read, a file format of image datato be generated, a color/monochrome setting, resolution, a compressionformat, and a compression ratio. The control unit 10 reflects thereceived setting information as a default in the setting/editing screenfor the setting information shown in FIG. 7. This makes it highlypossible that a user touches the touch panel on the scan start button toexecute scanning without performing an operation for altering settingdetails in the screen shown in FIG. 7.

In addition, the control unit 10 of the MFP 1 may require information ofa transmission destination of image data obtained by image processingexecuted by a mobile scan, that is, the image reading unit 15. In a casewhere the transmission destination is specified as the connectedcommunication device 2, the information of the transmission destinationmay be an e-mail address or a telephone number of the communicationdevice 2 other than network identification information issued by the MFP1. In a case where the transmission destination is specified as acommunication device other than the connected communication device 2,the information of the transmission destination may be an e-mail addressor a telephone number of this other communication device. When the MFP 1connects to a LAN in an enterprise, a public facility or a house througha communication function other than the communication unit 14 andanother communication device similarly connects to the LAN, theinformation of the transmission destination may be an IP address of thisother communication device within the LAN. In a case where thetransmission destination is specified as a recording device which isconnectable to the communication device 2 and another communicationdevice, the information of the transmission destination may be an IPaddress or the like of the recording device.

Moreover, the control unit 10 of the MFP 1 requests image data as to beprinted out when executing image processing by a mobile print, that is,the image forming unit 16. The control unit 10 at this moment receives aconnection request including a request of executing printing from thecommunication device 2. The control unit 10 may also request a listcomposed of compressed thumbnails or image data itself. Moreover, thecontrol unit 10 may request setting information used in printing imagedata. The setting information for printing may be a print size setting,a color/monochrome setting, a printing quality setting or the like.Thus, a user may select an image to be printed from the list shown inthe display unit 11 a of the MFP 1 and perform an operation of printstart without performing an operation for causing the communicationdevice 2 to transmit image data.

In addition, the control unit 10 of the MFP 1 may request addressinformation in order to add information received from the communicationdevice 2 in an address book of the MFP 1 as the information of atransmission destination of image data obtained by image processingthrough a mobile scan, that is, the image reading unit 15. In a casewhere the transmission destination is specified as a communicationdevice other than the communication device 2 and with addressinformation registered in the communication device 2, the user'soperation can be simplified by adding the address information registeredin the communication device 2 to the address book data in the MFP 1 asthe transmission destination.

Embodiment 3

According to Embodiment 3, the MFP 1 detects the connection with thecommunication device 2 and alters to the operation screen as shown inthe screen example of FIG. 6, and the control unit 10 requests thecommunication device 2 to transmit information corresponding to eachoperation in a case where the touch panel on an icon 114, an icon 115 oran icon 113 is touched.

A hardware configuration in an image processing system according toEmbodiment 3 is similar to the configuration according to Embodiment 1.Accordingly, the configuration units common to those in Embodiment 1 aredenoted by the same reference numerals and will not be described indetail.

FIGS. 9A and 9B are flowcharts showing an example of a processingprocedure to be executed in the MFP 1 according to Embodiment 3.

The control unit 10 of the MFP 1 determines whether a connection requestfrom the communication device 2 has been received through thecommunication unit 14 (Step S301). If the control unit 10 determinesthat the connection request has not been received (S301: NO), thecontrol unit 10 returns processing to Step S301, and then waits until itis determined that the connection request has been received.

Meanwhile, the control unit 20 of the communication device 2 searchesfor an access point, that is, the communication unit 14 of the MFP 1,obtains identification information such as SSID of the MFP 1, andtransmits a connection request to the MFP 1 based on the obtainedidentification information. The control unit 20 may be configured toobtain SSID of the MFP 1 directly inputted by a user through theoperation unit 21 b without performing a search.

At Step S301, if the control unit 10 determines that the connectionrequest has been received (S301: YES), the control unit 10 issuesnetwork identification information of the communication device 2 toestablish a wireless communication connection with the communicationdevice 2 (Step S302), and transmits the network identificationinformation to the communication device 2 (Step S303). Specifically atStep S302, the control unit 10 assigns an IP address. Therefore, awireless communication connection is established between the MFP 1 andthe communication device 2.

Next, the control unit 10 alters the operation screen displayed in thedisplay unit 11 a to an operation screen related to image processingbased on the information transmitted/received to/from the communicationdevice 2 (Step S304). The operation screen after alternation to bedisplayed here is similar to the screen example shown in FIG. 6according to Embodiment 1.

The control unit 10 accepts an operation through the operation screenafter alternation (Step S305). The control unit 10 determines whether afunction selected by the operation accepted through the operation unit11 b is any of the “mobile scan,” “mobile print,” and “address list”(Step S306).

At Step S306, in a case where the control unit 10 determines that the“mobile scan” is selected (S306: mobile scan), the control unit 10requests the communication device 2 to transmit setting information usedwhen executing image processing by the image reading unit 15 (StepS307). The control unit 10 determines whether the requested settinginformation has been received from the communication device 2 (StepS308). If the control unit 10 determines that the requested settinginformation has not been received (S308: NO), the control unit 10returns processing to Step S308, and then waits until it is determinedthat the requested setting information has been received. If the controlunit 10 determines that the requested setting information has beenreceived (S308: YES), the control unit 10 alters the operation screendisplayed in the display unit 11 a based on the received settinginformation (Step S309). The operation screen after alternation in StepS309 is a screen as shown in FIG. 7 according to Embodiment 1, and it ischanged so as to reflect the content of the received settinginformation. Therefore, by a user only touching the touch panel on theicon 114 named “mobile scan” at Step S305, the user can get the displayof the scan start button for starting scanning based on the settinginformation stored in the communication device 2, and the operation canbe simplified.

The control unit 10 may also accept an alternation in setting throughthe operation unit 11 b based on the received setting information (StepS310). The control unit 10 executes image reading (scanning) by theimage reading unit 15 based on the setting indicated by the receivedsetting information or the setting received at Step S310 (Step S311),and transmits image data generated by the image reading unit 15 to thecommunication device 2 (Step S312).

The control unit (preparing unit) 10 prepares reference information suchas path information inside the storage unit 13 which can be shared withother communication device so as to be able to obtain image datagenerated by the image reading unit 15 from the other communicationdevices in addition to transmission of the image data to thecommunication device 2 (Step S313). The control unit 10 transmits theprepared reference information to the communication device 2 (StepS314), and terminates processing related to a mobile scan function. Thereference information in Step S313 may be an e-mail address, a telephonenumber or the like of such another communication device itself, or itmay be path information on a sharable recording device other than thestorage unit 13. The image data generated by processing of Step S311 maybe transmitted to a server in order to be recorded on the serverexpressed by a URL (Step S312), the URL may be prepared as referenceinformation and transmitted to the communication device 2. In addition,in a case where the MFP 1 connects to a LAN in an enterprise, a publicfacility or a house connected through a communication function otherthan the communication unit 14, and the transmission destination of thegenerated image data is specified as a communication device, a server ora recording device within the LAN, pass information and URL informationfor obtaining image data from such transmission destination may beprepared as reference information and may be transmitted to thecommunication device 2.

At Step S306, if the control unit 10 determines that the “mobile print”is selected (S306: mobile print), the control unit 10 requests thecommunication device 2 to transmit a list (image identificationinformation, thumbnails or the like) of image data to be printed inorder to execute image processing by the image forming unit 16 (StepS315). The control unit 10 determines whether the requested list ofimage data has been received from the communication device 2 (StepS316). If the control unit 10 determines that the requested list ofimage data has not been received (S316: NO), the control unit 10 returnsprocessing to Step S316, and then waits until it is determined that therequested list of image has been received. If the control unit 10determines that the requested list of image data has been received(S316: YES), the control unit 10 alters the screen so as to display alist of image data (thumbnails) in the display unit 11 a based on thereceived list (Step S317).

FIG. 10 is an explanatory view showing an example of a screen displayingthe list of image data in Embodiment 3. In the example shown in FIG. 10,the thumbnails of the image data received from “mobile 1” being theidentification information of the communication device 2 are listed anddisplayed. It is possible for a user to select any one of the thumbnailsbeing displayed.

The description continues with reference again to the flowcharts inFIGS. 9A and 9B.

The control unit 10 accepts an operation for selecting image data by auser touching the touch panel on the screen displayed at Step S317through the operation unit 11 b(Step S318), and requests thecommunication device 2 to transmit the selected image data (notthumbnails) (Step S319). The control unit 10 determines whether therequested image data has been received from the communication device 2(Step S320). If the control unit 10 determines that the requested imagedata has not been received (S320: NO), the control unit 10 returnsprocessing to Step S320, and then waits until it is determined that therequested data has been received. If the control unit 10 determines thatthe requested image data has been received (S320: YES), the control unit10 executes printing based on the received image data by the imageforming unit (printing unit) 16 (Step S321), and terminates processingrelated to a mobile print function.

Therefore, by only the operation in which a user operates thecommunication device 2 for connecting to the MFP 1 and touches the touchpanel on the icon 115 named “mobile print” in the operation screen afteralternation to be displayed in the display unit 11 a of the MFP 1, theuser can get the operation screen shown in FIG. 10. As a user touchesthe touch panel on the print start button in a state of selecting adesired image from a list of image data as shown in FIG. 10, a printingof the selected image data can be executed in the MFP 1. In this way, itis possible to simplify the user's operation.

At Step S306, in a case where the control unit 10 determines thatwhether the “address list” has been selected (S306: Address List), thecontrol unit 10 requests the communication device 2 to transmit addressinformation in order to execute processing for registering the addressinformation (information in an address book) obtained from thecommunication device 2 into the MFP 1 (Step S322). The control unit 10determines whether the requested address information has been receivedfrom the communication device 2 (Step S323). If the control unit 10determines that the requested address information has not been received(S323: NO), the control unit 10 returns processing to Step S323, andthen waits until it is determined that the requested address informationhas been received. If the control unit 10 determines that the requestedaddress information has been received (S323: YES), the control unit 10alters the display screen to an address list display screen including anicon for displaying the received address information. (Step S324).

FIG. 11 is an explanatory view showing an example of a screen displayingan address list in Embodiment 3. In the example shown in FIG. 11, theaddress information preliminarily registered in the MFP 1 is displayedin alphabetical order. In the example shown in FIG. 11, the addressinformation includes identification information (name) of thedestination, telephone number and e-mail address. Through the processingin Step S324, the icon 116 named “mobile” for displaying the addressinformation received from the communication device 2 is displayed in thedisplay of an address information list.

FIG. 12 is an explanatory view showing an example of a screen displayinga list of address information received from the communication device 2.In the screen example shown in FIG. 11, in a case where a user touchesthe touch panel on the icon 116, the control unit 10 detects the actionthrough the operation unit 11 b and displays the screen example shown inFIG. 12. In the example of FIG. 12, a list of the address informationreceived from “mobile 1” being the identification information of thecommunication device 2 is displayed. In the example of FIG. 12, thecontrol unit 10 receives e-mail addresses of the destinations “user 1”and “user 2” from the communication device 2 at Step S323. A user isable to select either the address information of the “user 1” in displayor that of the “user 2” in display. When a user selects the addressinformation by touching the touch panel on any of address informationand touches the touch panel on the register-button displayed in the samescreen, the control unit 10 detects that the address information hasbeen selected and then executes registration processing.

The description continues with reference again to the flowcharts inFIGS. 9A and 9B.

The control unit 10 accepts a selection of the address information to beregistered among the address information received from the communicationdevice 2 (Step S325). The detail of processing at Step S325 is realizedby detecting the selection of address information and the touch on theregister-button in the display screen of the list of address informationreceived from the communication device 2 as described above. The controlunit 10 adds and stores the selected address information into theaddress book of the storage unit 13 (Step S326), and terminatesprocessing of registering address information based on the informationfrom the communication device 2.

Therefore, by the operation in which a user operates the communicationdevice 2 for connecting to the MFP 1 and touches the touch panel on theicon 113 named “address list”, the user can get the operation screenwith the display of the icon 116 named “mobile.” After the user touchesthe touch panel on the icon 116, with the operation of selecting desiredaddress information and then touching the register-button, the addressinformation registered in the communication device 2 can be registeredinto the MFP 1. Since the MFP 1 automatically obtains addressinformation from the communication device 2 and displays a screen fordisplaying the obtained address information and accepting a selection ofthe address information, the user's operation can be simplified.

Embodiment 4

According to Embodiments 1 to 3, the processing for simplifying anoperation with proper alternation of an operation screen in a case wherethe communication device 2 is connected to the MFP 1 is described.According to Embodiment 4, the processing for altering an operationscreen in a case where the communication between the communicationdevice 2 and the MFP 1 has been cut off is described below.

A hardware configuration in an image processing system according toEmbodiment 4 is similar to the configuration according to Embodiment 1.Accordingly, the configuration units common to those in Embodiment 1 aredenoted by the same reference numerals and will not be described indetail.

FIG. 13 is a flowchart showing an example of a processing procedure tobe executed in the MFP 1 according to Embodiment 4. After establishing acommunication connection between the communication device 2 and the MFP1 as described in Embodiments 1 to 3, the processing procedure shown inFIG. 13 is periodically executed independently from the processing shownin FIGS. 3, 8, 9A and 9B.

The control unit (cut-off detecting unit) 10 of the MFP 1 determineswhether the communication with the communication device 2 has been cutoff through the communication unit 14 (Step S41).

At Step S41, if the control unit 10 determines whether the connectionhas been cut off (S41: YES), the control unit 10 accepts a selection ofwhether returning the operation screen is executed (Step S42).Specifically at Step S42, the control unit 10 displays, in the displayunit 11 a, a screen (dialog) for accepting the selection of whetherreturning the operation screen is executed. FIG. 14 is an explanatoryview showing an example of a screen displayed in the MFP 1 in a casewhere it is determined that the communication with the communicationdevice 2 has been cut off. In the example of FIG. 14, a messageindicating the cut-off of connection with the communication device 2 anda message for inquiring whether the information obtained from thecommunication device 2 is stored in the MFP 1 are displayed. In a casewhere “YES” is selected here, the selection is made which indicates notreturning the operation screen to the initial screen (see FIG. 4). Onthe contrary, in a case where “NO” is selected, the selection is madewhich indicates returning the operation screen to the initial screen.

The description continues with reference again to the flowchart in FIG.13.

At Step S42, the control unit 10 determines whether the selectionindicating returning the operation screen has been made (Step S43). Ifthe control unit 10 determines that the selection indicating returningthe operation screen has been made (S43: YES), the control unit 10interrupts processing which has been executed at that point and returnsthe operation screen to the initial screen (a predetermined operationscreen) (Step S44), and then terminates processing. At Step S44, inaddition to the processing of returning the operation screen to theinitial screen, the control unit 10 may delete the informationtemporarily stored in the temporary storage unit 12.

If the control unit 10 determines that the selection indicatingreturning the operation screen has not been made (S43: NO), the controlunit 10 terminates processing. In this case, the display of theoperation screen after alternation is maintained.

In this way, since the MFP 1 returns the operation screen to the initialscreen automatically when the communication connection with thecommunication device 2 has been cut-off, the user's operation can besimplified. As shown in the above-described processing procedure, sincethe MFP 1 accepts a selection of whether returning to the initial screenis executed, even when a communication connection has been cut offagainst the intention of a user, it is also possible to prevent acomplicated operation. For example, with regard to this situation, theremay be a case that, even when the connection has been cut off, a userwishes to store the address information into the MFP 1. In addition,there may be a case that, even if a communication connection has beencut off, the user wishes to continue the printing based on the imagedata once transmitted to the MFP 1. In the configuration having need oftransmitting/receiving image data again when the connection has been cutoff due to failure of communication on the way, the user's operationbecomes complicated. In addition, there may be a case that, even if acommunication connection has been cut off, a user wishes to continueprocessing such as transmitting image data generated by a scan toanother recording device. Also in this case, even if the connection hasbeen cut off due to failure of communication on the way, if thetransmission destination is not the communication device 2, there is noproblem in continuing processing. Furthermore, even if the transmissiondestination is the communication device 2, there may be a case that auser wishes to execute the transmission of image data if the connectionwith the communication device 2 is established again within apredetermined time period.

In addition, at Step S41, if the control unit 10 determines that theconnection with the communication device 2 is effective and has not beencut off (S41: NO), the control unit 10 determines whether a certainperiod of time (for example, 5 minutes) has elapsed from a recentoperation (Step S45). If the control unit 10 determines that the certainperiod of time has not been elapsed (S45: NO), the control unit 10returns processing to Step S41. If the control unit 10 determines thatthe certain period of time has been elapsed (S45: YES), the control unit10 determines that the operation has been interrupted, and returns theoperation screen to the initial screen (S44) and then terminates theprocessing. Also in this case, the control unit 10 may also delete theinformation temporarily stored in the temporary storage unit 12.

In this way, in a case where a certain period of time has been elapsedwithout any operation, since the MFP 1 determines that the operation hasbeen interrupted and then automatically returns to the initial screen,it is possible to prevent the occurrence of situations such as acceptingan erroneous operation made by a different user related to theinterrupted operation.

Embodiment 5

According to Embodiments 1 to 4, when the communication device 2 isconnected to the MFP 1 displaying an initial screen (see FIG. 4) in thedisplay unit 11 a, the MFP 1 is configured to alter the initial screento an operation screen related to processing based on the informationtransmitted/received to/from the communication device 2. On the otherhand, in Embodiment 5, the MFP 1 is configured not to accept anoperation even if the MFP 1 displays an initial operation screen indisplay unit 11 a until the communication device 2 is connected to theMFP 1.

A hardware configuration in an image processing system according toEmbodiment 5 is similar to the configuration according to Embodiment 1.Accordingly, the configuration units common to those in Embodiment 1 aredenoted by the same reference numerals and will not be described indetail.

FIG. 15 is a flowchart showing an example of a screen alternationprocedure to be executed in the MFP 1 according to Embodiment 5.

The control unit 10 of the MFP 1 determines whether a connection requestfrom the communication device 2 has been received through thecommunication device 14 (Step S51). At this time point, for example, anoperation screen is assumed not to be displayed in the display unit 11a. It is noted that an operation screen may be displayed with lowerdisplay luminance or the like.

If the control unit 10 determines that the connection request has notbeen received (S51: NO), the control unit 10 determines whether theoperation unit 11 b has been operated (Step S52). At Step S52, thecontrol unit 10 determines that the operation unit 11 b has beenoperated in a case where the touch panel of the operation unit 11 b istouched or in a case where any of hardware keys is pressed down. If thecontrol unit 10 determines that the operation unit 11 b has not beenoperated (S52: NO), the control unit 10 returns processing to Step S51and then waits.

At Step S52, if the control unit 10 determines that the operation unit11 b has been operated though not receiving the connection request (S52:YES), the control unit 10 displays a message indicative of not acceptingan operation in the display unit 11 a(Step S53). The control unit 10returns processing to Step S51 and then waits. FIG. 16 is an explanatoryview showing an example of a message to be displayed in the display unit11 a in Embodiment 5. As shown in FIG. 16, a message indicating that theMFP 1 is not available until the communication device 2 is connected tothe MFP 1 is displayed in the display unit 11 a. Therefore, until thecommunication device 2 is connected to the MFP 1, the MFP 1 does notaccept an operation and does not execute image processing even if a usertouches the operation unit lib.

The description continues with reference again to the flowchart in FIG.15.

If the control unit 10 determines that the connection request has beenreceived (S51: YES), the control unit 10 issues network identificationinformation of the communication device 2 in order to establish awireless communication connection with the communication device 2 (StepS54), and transmits the network identification information to thecommunication device 2 (Step S55). Therefore, a wireless communicationconnection is established between the MFP 1 and the communication device2.

Next, the control unit 10 alters the operation screen displayed in thedisplay unit 11 a to an operation screen (FIG. 6) related to imageprocessing based on the information transmitted/received to/from thecommunication device 2 (Step S56), and then waits. Subsequently, in acase where a user touches the operation unit lib, the control unit 10can accept an operation.

The control unit 10 accepts an operation corresponding to the displayedoperation screen (Step S57), executes image processing of scanning bythe image reading unit 15 or of printing by the image forming unit 16(Step S58) in response to the accepted operation, and then terminatesprocessing.

Therefore, only when a user carrying the communication device 2activates a print scanning application and connect the communicationdevice 2 to the MFP 1, the user can operate the MFP 1. Accordingly, itis possible to prevent complication of an operation related to imageprocessing.

Embodiment 6

According to Embodiment 6, in a case where the MFP 1 is connected to thecommunication device 2, the MFP 1 alters an operation screen to a screen(custom menu) uniquely corresponding to the communication device 2.

A hardware configuration in an image processing system according toEmbodiment 6 is similar to the configuration according to Embodiment 1,except for the information described later which is stored in thestorage unit 22 of the communication device 2. Accordingly, theconfiguration units common to those in Embodiment 1 are denoted by thesame reference numerals and will not be described in detail.

In the flash memory of the storage unit 22 of the communication device 2according to Embodiment 6, UI (User Interface) definition informationfor defining the configuration of the operation screen for operating thecommunication device 2 in the MFP 1 is stored in association with theprint scanning application. The UI definition information is informationdescribed in, for example, an HTML format, an XML format or the like. Inthis case, the MFP 1 includes a web browser function, and the MFP 1reads out the UI definition information transmitted from thecommunication device 2 through the web browser function, and thengenerates and displays an operation screen for the communication device2.

The procedure in which the MFP 1 uniquely alters an operation screen inassociation with the communication device 2 with the use of such UIdefinition information is described below.

FIG. 17 is a flowchart showing an example of a processing procedure tobe executed in the image processing system according to Embodiment 6.

The control unit 20 of the communication device 2 searches for an accesspoint through the communication unit 23 in a case where the printscanning application is activated (Step S601). The control unit 20displays information of the access point being a search result in thedisplay unit 21 a (Step S602), and accepts a selection of an accesspoint corresponding to the MFP 1 (Step S603). The control unit 20transmits a connection request to the access point (communication unit14) of the MFP 1 (Step S604). At Step S604, in a case where imageprocessing to be executed in the MFP 1 such as scanning or printing isdetermined, the control unit 20 of the communication device 2 transmitsa connection request including an execution request indicating thedisplay of the custom menu corresponding to the content of the imageprocessing.

The control unit 10 of the MFP 1 receives the connection request fromthe communication device 2 (Step S605), and issues networkidentification information of the communication device 2 in order toestablish a wire communication connection with the communication device2 (Step S606). The control unit 10 transmits the issued networkidentification information to the communication device 2 (Step S607).

The control unit 20 of the communication device 2 receives thetransmitted network identification information (Step S608). Therefore, awireless communication connection is established between the MFP 1 andthe communication device 2.

The control unit 10 of the MFP 1 determines whether obtaininginformation related to the custom menu from the communication device 2is required based on the connection request (Step S609). Specifically,the control unit 10 determines that the information of the custom menuis necessary in a case where an execution request indicating the displayof the custom menu is included in the received connection request.

If the control unit 10 determines that obtaining information is notnecessary (S609: NO), the control unit 10 alters the screen displayed inthe display unit 11 a to an operation screen, which is setpreliminarily, related to image processing based on the informationtransmitted/received to/from the communication device 2 (Step S610), andthen waits. The operation screen is, for example, a screen (see FIG. 6)with increased functions which can be selected in response to theconnection of the communication device 2.

At Step S609, if the control unit 10 determines that the obtaininginformation related to the custom menu is necessary (S609: YES), thecontrol unit 10 transmits a transmission request of the UI definitioninformation to the communication device 2 (Step S611).

In the communication device 2, the control unit 20 receives thetransmission request of the UI definition information from the MFP 1through the communication unit 23 (Step S612), reads out the UIdefinition information stored in the flash memory of the storage unit 22and then transmits the UI definition information to the MFP 1 (StepS613).

The control unit 10 of the MFP 1 receives the UI definition informationrequested at Step S611 (Step S614), and temporarily stores the receivedUI definition information in the temporary storage unit 12 (Step S615).The control unit 10 generates an operation screen based on the receivedUI definition information and alters the screen to the generatedoperation screen (Step S616), and then waits.

Therefore, only by a user connecting the communication device 2 carriedby him/herself to the MFP 1, the operation screen of the MFP 1 can bealtered to the user interface matched to the utilization purpose of auser who carries the communication device 2. Since the operation screenfor a service actually used by a user is directly displayed, theoperation can be simplified.

The processing shown in the above-described Embodiments 1 to 6 can alsobe implemented by combination with other embodiments.
